Two tests about validation is skipped silently. For more details see mitsuhiko/flask#485
The goal is to make setup.py test use unittest2 instead of unittest.
The problem of existing implementation here jfinkels@aed13d5 is that setup.py test does not install neither test requirements, nor the one needed for flask-restless.
Tests added in c3489c5 will also have this problem.
I think this is no longer an isue.
